#414 ZOrder Problem on DirectX and SMaterial::PolygonOffsetFactor

[Tirus]

I've tried to make a simple decal manager.
For placing them i have used on the decal SMaterial PolygonOffsetFactor = 1.
It works well with OpenGL (no ZOrder problem, and no flicker), but on DirectX9 the decal is visibile thru anything else.
(I work with Irrlicht 1.8)

Please provide a simple code demonstrating the problem, otherwise we cannot debug the situation.
